Which determiner can be used in the following sentences? 1. I'd like (a / some) coffee. 2. I'd like (a / the / some) tea with lemon. 3. Can I have (a / the / some) tea with milk? 4. Would you like (a / the / some / your) with lemon or milk?

I know that "milk" and "coffee" are uncountable nouns. So I would use "some". 1. I'd like some coffee. 2. I'd like some tea with lemon. 3. Can I have some tea with milk?

But I saw "a tea" that I think means "a cup of tea". But I'm not completely sure that these sentences would be correct. 1. I'd like a coffee. 2. I'd like a tea with lemon. 3. Can I have a tea with milk?

In the fourth sentence I would use "your". 4. Would you like your with lemon or milk?
